ZONA
Asymmetric reinforced tubes for top of the range, custom,
competitive road and MTB frames.
Material:
- Nivacrom for Zona. Nivacrom is
patented by Columbus. This is a steel alloy in which Vanadium and
Niobium, precipitate in the metal matrix, and block the grain growth
normally produced by overheating of the weld, and resulting in a
decline of mechanical characteristics, this even at temperatures above
1000 C. The material developed for the Zona series is subjected to a
series of operations and treatments that after drawing, homogenize the
mechanical characteristics of the tube, making them uniform along the
longitudinal axis.
- Mechanical Characteristics: Rm =
1000N/mm2, Rs = 920 N/mm2, AP5>10%
Characteristics of the Zona Tubes
- Non symmetrial tubes with cylindrical
butts.
- Moderate weight and notable strength
thanks to the newshapes, which are introduced for the first time also
for the tubes of the rear triangle.
- Elevated reliability and fatigue life.
Reasons to Choose Zona
- Athlete: Zona is the design
which finally allows for a reasonable compromise between weight,
strength and life of the frame. Thanks to the particular operations to
which Nivacrom is subjected and to the new sizes that also stiffen the
frame laterally by means of suitable grooves, it is possible to obtain
an end product with good characteristics of lightness and high
efficiency.
- Framebuilder: Zona allows for
the construction of reliable frames which are easy to realize, both in
the working of the tubes, the welding and the squaring operations of
the frame. Zona takes full advantage of the characteristics of
Nivacrom steel which has been especially developed for cycling.
The weight refers to sized and
mitered tube for a 54cm c-c road frame or a 18" (45.5cm) ATB
frame
